SHEET PACKING
w
TEFLON
(Polytetraflouroethylene)
Extremely
good chemical resistance to a wide range of fluids;
there are only a few very rare fluids that will attack it.
Has a very low static coefficient of friction (slippery), poor
heat conductor, good heat insulator.
It has a high coefficient of thermal expansion, swells
significantly under heat, will flow (creep) under relatively low loads
even at room temperature (cold flow).
Temperature: - 400 F to
500 F
w PRESSED
WOOL FELT
Made
from wool, compressed with chemical moisture and heat to enable the
natural tendency of wool fiber to interlock tightly when wet.
Wool felt is used for cushioning & padding, gasketing &
sealing, wicking & lubrication, vibration & shock control and
wicking.
w
FLEXIBLE
GRAPHITE SHEET
Manufactured
in various forms which include bonding of 316 Stainless Steel foil,
polyester or low carbon steel. Each
carries different temperature ratings.
Graphite is found in nature and is one of the two crystalline
forms of the element carbon, the other being the diamond.
Graphite has many unusual features which include a nature
lubricity; one of the most stable and chemical resistant materials in
the world. It has a high
temperature rating and an excellent conductor of heat and electricity.
w
CLOSED
CELL SPONGE
Closed cell cellular rubber products are good for insulation, floor
backing, and window and door seals.

TACKY CLOTH
(Wire
Inserted Rubberized Fiberglass)
A
fabric made from a texturized fiberglass yarn which is coated and
impregnated with a white rubber compound and has been twisted with a
brass wire for additional strength and density.
This gasket material is used for boiler gaskets, groove
packing, tapes, etc. It
is good for applications
where rough or uneven flanges need a sealing material.
Temperature: 300 F to 550
F
w
NEO/RUBBER
CORK
A
wide variety of uses dependent upon the style of rubber used.
Industrial, automotive, and transformer gasketing.
w VEGETABLE
FIBER
A
highly compressible, special blend of cellulose fibers treated with a
glue-glycerin binder rendered insoluble by means of a tanning solution
which gives it strong, flexible, oil proof properties excellent
sealing ability. It is highly conformable to compensate for
distortion in flanges making it an excellent and economical general
purpose gasket material.
Temperature up to 250 F
The premium grade of elastomeric binder and resin system with good
dimensional stability, fluid resistance and flexibility.is a
non-asbestos,
high density gasket material with fibrous reinforcement for higher
temperature applications.
Temperature up to 480 F
